COM object with CLSID {88578679-272B-40C0-B1FD-C3409381A450} is either not valid or not registered.

I recently moved my local dev website from one laptop to another. My website uses very old versions of Persits ASPPDF.dll and ASPENCRYPT.dll. Since rebuilding the application, I'm getting the following error:

When I moved the dll's I just copied them over, I didn't do any sort of install on them. I am pretty sure they are COM, not .NET components. Do I need to track down the original install and reinstall them for this to work or can I fix this some other way? I won't have access to the original installs until next week.
